Quit buggin' me
An easier way has been posted up here a few times.
Using the 12"x12" known object in your image -> draw a rectangle over it.
Mask the image using the box you just drew.
Scale the box up (lock the aspect ratio) to the real size 12"x12" size.
Unmask the image -> it will be the correct (full) size.
I'd work on it at full scale. No need to scale up and down unless your system starts to slow down as the layout gets more complicated.
